Aspecial electronic sensor is embedded in the seat of a car that takes riders around a circular loop-the-loop ride at an amusement park. the sensor measures the magnitude of the normal force that the seat exerts on a rider. the loop-the-loop ride is in the vertical plane and its radius is 21.0 m. sitting on the seat before the ride starts, a rider is level and stationary, and the electronic sensor reads 730. n. at the top of the loop, the rider is upside down and moving, and the sensor reads 360. n. what is the speed of the rider at the top of the loop?
